The Distributed Replicated Block Device (DRBD) is a distributed storage system for the GNU/Linux platform. It consists of a kernel module, several userspace management applications and some shell scripts and is normally used on high availability (HA) clusters. DRBD bears similarities to RAID 1, except that it runs over a network.
DRBD refers to both the software (kernel module and associated userspace tools), and also to specific logical block devices managed by the software. DRBD device and DRBD block device are also often used for the latter.
Status
DRBDv8 is up and running with LIO Target r293 and a patch set (iblock-bio_add_page-v5_C). RisingTide Systems software deeply integrates LIO.
